titleOfInvention | Biodegradable injectable filler, preparation method and application thereof |
abstract | The present invention provides a biodegradable injectable filler, a preparation method and application thereof, and especially an injectable implant composition and a preparation method thereof, wherein the composition contains biodegradable polymer particles and the content thereof Not higher than 0.1% hyaluronic acid. Hyaluronic acid significantly improves the hydrophobic properties of the surface of the PLLA polymer scaffold, promotes the adhesion and growth of collagen cells on its surface, significantly improves the filling effect or filling effect of the composition, removes wrinkles, and enhances the aesthetics of facial skin, which is beneficial to improve PLLA particles in freeze-drying. The suspension stability after reconstitution is beneficial to reduce the hydrolysis and degradation of the PLLA ester bond, and reduce the swelling, inflammation, allergic reactions and other adverse reactions that may be caused by acidic degradation products. |
